From 666feb21a0083e5b29ddd96588553ffa0cc357b6 Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Tue, 10 Apr 2018 16:30:03 -0700 Subject: mm, migrate: remove reason argument from new_page_t No allocation callback is using this argument anymore. new_page_node used to use this parameter to convey node_id resp. migration error up to move_pages code (do_move_page_to_node_array). The error status never made it into the final status field and we have a better way to communicate node id to the status field now. All other allocation callbacks simply ignored the argument so we can drop it finally.
